Hf Board Guidelines Updated

HF board was brought down, as there were few security issues that had to be fixed urgently. The site is up and running now.

We also took this opportunity to update the HF Guidelines and put in a disclaimer. Points from 3.0.16 to 3.0.19 have been added newly. If any of you have any doubts or questions related to it, please PM the admin. We request all the members to adhere to the HF Guidelines and continuing on HF would mean your acceptance to the guidelines.
